IMPROVEMENT IN -MAOHINS FOR GUTTING BUNGS.

TO lALL WHOM IT CONCERN:

Be it known that I, JoHN GEORGE Scniumr, of Rochester, county of Monroe, and State of New York, have inv'ented new and useful improvements on my Machine for Cutting Bnngs for barrels, forwhich machine I received Letters Patent, which bear date December 11, 1866, No` 60,430; and I do hereby declare that the following is a full and exact descriptionthercof, reference being had to the uecompnnying drawings and to the letters of reference marked thereon, .in which- Figure 1 representsa front view of my machine.

Figura 2 represents a longitudinal view of yielding centre b.

Figure 3 represe nlts the circular plate h, under side.

Figure 4 reprcsents the upper sideofcircular plate h.

The nature of my invention consists ivn using but one spring instead of two, as claimed in my Letters Patent bearing date the 11th day of December, 1866, No. 60,430, for holding the' knife i; also in tliscarding Ithe screws g g, andsnh'stituting thcrefor the safety-plates o o, and gauge k, and in making holes through the mandrel, as shown'atf'mv'nt m', in fig. 1, and through the head of yielding centrc; as'shown utq, in fig. 2.

To enable otl1ers' fslille1 in the art to make and use my invention, I will proeeerl to describe its construction and operation; v I i 'I construct my Safety-plates o o of steel, which are fitted close to the out-side edge of circular plate h, and made fast to the same by means of screws 8 8 8 s, ns seen in figs. 1 and 3; The gaugc k is also made of steel, with a square frame to admit the k'nife and guide the same when the machine is worked. The opening inside of gauge er frame his-'large enough to allow the knife the necessary roomto move to and from the yiclding centre b. On one 'endjof the square frame 7a i's a screw cut, p. Said screwp passes lthrough a hole in guide-plate o, with nuts on either'side of guide-plate o, us seen in figs. 1 and 4. The gauge k, With square frame, screw 2), ancl the two nuts (ze,v are for the purpose of regulating the size ofv the bung'to .he cut, and to pre'v'ent the knifc from moving tooffar-away from the centre b. I also improve the yielding;v centre b of my machine by arran ging the same in such a manner that it may be x'uised or lowered by shifting thc pin 'lt to either of the holes i 'm m m, so as to suit the length of the'knife or the thickness of the Wood.

What I claimS-e-s my invention, and desire to secure by Letters Patent, is-Q i 1. I claim the safety-plates'o o, in connection with gauge k, screw p, and nuts e e, all for the purpose and in the manner herein dc-scribed. i

2. I claim the'head q, of yielding centre b, With hole m, the holes -m m m in m'androl a, and the pin n, ail

for the Purpose and in the manner herein (lescribed.
